Title: Carbon monoxide removal
Inventor: VAN KEULEN ARJAN NICOLAAS JOHA
IPC: H01M8/06
Filed: 1997-09-09
Granted: 2005-08-02
Abstract: A process for removing carbon monoxide from a gas stream containing hydrogen, carbon monoxide and carbon dioxide comprising subjecting the gas stream to a first stage high temperature selective catalytic methanation to lower the carbon monoxide concentration in the gas but not below a concentration which allows carbon dioxide methanation to take place followed by a second stage low temperature selective catalytic methanation to lower the residual carbon monoxide in the gas stream to a concentration below 40 ppm. The high temperature methanation is suitably carried out at a temperature between 250 °C and 350 °C and the low temperature methanation is suitably carried out at a temperature below 270 °C.
Patent CA-2272820-C (CA)

Granted: 2012-09-11
Abstract: L'invention se rapporte à la nécessité d'améliorer les rendements de vecteurs viraux obtenus par des procédés de culture cellulaire. Il a été démontré en particulier que pour les adénovirus, l'utilisation de vitesses de perfusion faibles à moyennes dans un système de culture cellulaire fixe permettait d'assurer un meilleur rendement. Dans d'autres modes de réalisation, les inventeurs ont démontré une production améliorée d'Ad-p53 avec des cellules cultivées dans un milieu sans sérum, et en particulier dans une culture en suspension sans sérum. L'utilisation d'une lyse par détergents constitue également un facteur important dans l'accroissement des rendements. Lorsque les aspects de l'invention sont combinés les virus peuvent être purifiés en une seule étape chromatographique, ce qui permet d'obtenir des virus purifiés ayant la même qualité que des préparations formées à partir de double bandage CsCl au moyen d'une ultracentrifugeuse.

Abstract: A duty dithering method for use with electronic support measures and radar warning receivers, and the like, that provides for improved probability of intercept at low utilization levels. The electronic support measures (ESM) system and radar warning receiver are controlled by a multi-system sensor manager having an ESM scheduler. In accordance with the present method, a maximum duty cycle is chosen for the ESM  system. The chosen duty cycle is allocated to the ESM system each frame by the ESM scheduler. At the beginning of each frame, the ESM scheduler picks a random offset and subtracts it from the maximum duty to compute an ESM duty for that frame.      The ESM scheduler commands data collections based on the computed duty for that frame. This step is repeated each frame.
